Preserve the health of your assets with the SDT200 ultrasound detector. Hear air leaks, trend and monitor the condition of your bearings, safely inspect electrical panels, and schedule repairs on your terms, long before they shut you down – all with ultrasound technology.


Control energy costs, predict failures, improve product quality, and increase overall production uptime. With your SDT ultrasound solution, you can predict and prevent failures before they occur. Stop relying on the reactive, fire-fighting maintenance measures of the past and start a proactive approach.


Detect, trend, and analyze asset health by viewing the ultrasound and vibration time signal and spectrum directly on the SDT340’s color display. Manage the results with UAS4.0, a scalable, multi-technology, multi-platform application that lets you access data from your desktop, server, or in the cloud.


LUBExpert is an ultrasound solution that helps you Grease Bearings Right. Use the right lubricant at the right location using the right intervals and the right quantities while receiving the right indication of a task well done, including bearing status.

SDT Checker Range

With a focused solution for every problem, the Checker range makes ultrasound available to everyone. Choose the right tool for the right job and perform fast troubleshooting inspections. As the first defense against breakdown, Checkers quickly and early identify defects, allowing for more in-depth analysis and trending with an SDT200, SDT270, or SDT340.
